Abstract: Abstract Of The Disclosure A well tool apparatus includes a housing adapted to be connected in a pipe string.  A mandrel is slid ably received in the housing and adapted to be selectively telescoped bet-ween first and second positions relative to the housing.          The mandrel has a slow passage there through and has a lateral bypass port communicating the flow passage with an exterior surface of the mandrel for allowing well fluids to bypass the flow passage of the well tool as the tool is being lowered into a well.  A reversible removable sliding sleeve is disposed about the exterior surface of the mandrel and is constructed to abut the housing and to be thereby moved from a first position wherein the bypass port is open to a second position wherein the bypass port is closed upon telescoping collapsing movement of the housing relative to the mandrel.  The sliding sleeve has a latch on one end thereof.  With the sleeve in a first orientation relative to the mandrel, the latch is arranged to engage a latch engage-ment of the mandrel so as to lock the bypass in a closed position upon the first telescoping collapsing movement of the tool.  In a second arrangement, the sliding sleeve is reversed in its position relative to the mandrel so that the latch of the sliding sleeve is always latched to the housing, thus providing a tool wherein the bypass port may be repeatedly closed and opened upon repeated telescoping collapsing and extending movements of the tool.  A final arrangement of the tool allows the bypass port and the sliding sleeve to be completely removed to eliminate the bypass.

Abstract: FREQUENCY MULTIPLIER        Abstract VLF communication signals encoded in MSK format contain phase ambiguities that must be resolved in order to use such signals in navigation systems. The ambiguities are resolved by the present frequency multiplying device that in one embodiment operates to double the frequency of an input signal and mix the doubled input signal with a mixing signal to produce an output signal having first and second states. The device includes a transition detector (42) for generating a trigger signal in response to each low-to-high orhigh-to-low transition of the input signal that occurs when the output signal is in its second state, and a bistable circuit (44) for generating the output signal in response to the trigger signal and to a mixing signal. The bistable circuit responds to the trigger signal to cause the output signal to be in its first state, and responds to a periodic characteristic of the mixing signal to cause the output signal to be in its second state. The transition detector may comprise a positive edge triggered flip-flop (50) and a negative edge triggered flip-flop (52). The bistable means may comprise a third flip-flop (56) having the mixing signal connected to its clock input and the trigger signal connected to its clear input. The frequency doubling device may also include means (58) for selectively disabling the second flip-flop so that the frequency of the input signal is not doubled.

Abstract: Abstract of the Disclosure An applicator unit is moved through a field of growing vegetation, for instance as an implement mounted across the front of a farm tractor.  The unit includes a horizontal, laterally extending outlet manifold ranked above a similarly arranged inlet manifold. Between each manifold a plurality of forwardly convex knee-like rod members are mounted.  In use, a treatment liquid to be directly applied to vegetation is arranged to run out of the outlet manifold in a superficial sheet along the surface of each rod.  As vegetation is grazed by the rods, some of the treatment liquid is wiped onto the vegetation.  Any treatment liquid which is not thus wiped onto vegetation is collected from the lower ends of the rods into the inlet manifold and pumped back up to a reservoir from which it flows to the outlet manifold.  By preference each knee like rod is disposed at an incline as seen in front elevation in order to decrease the chance that a tall thin plant can pass untreated between two adjacent rods.          A valving system is provided to prevent air entry on inlet side of the pump.

Abstract: Abstract In accordance with the invention a chemimechanical pulp is produced from lignocellulosic material, for example wood chips, by subjecting the material to a process in which it is steamed, impregnated with alkali and peroxide, drained, pre-heated, refined and bleached.  The material is impreg-nated in a single stage with a solution containing alkali and peroxide.  Subsequent to passing an intermediate drain-age and reaction stage, the material is pre-heated to a temperature of from about 50°C, but not above 100°C. The material is then refined in one or two stages.  The material can be impregnated by immersing the same in the impregnating solution for a period of up to 20 minutes at a temperature of 15-60°C, or by compressing the material in a screw press and permitting the compressed material to expand in the impregnating solution.  The ratio of alkali to peroxide in the impregnating solution is balanced so as to obtain a pH greater than 12.  The optimal brightness for a given peroxide charge is achieved by a balanced division of the peroxide charge between the chip impregnating stage and the bleaching stage.

Abstract: ABSTRACT         A jet pump macerator pump sewage handling system which provides a unique waste control system for use in mobile units such as passenger trains and ships in which multiple toilets are connected to a transfer manifold pipe which communicates with a non-clogging jet pump which is formed with a venturi and through which liquid material is driven by a macerator pump.  waste material from the toilets is drawn by the jet pump through the transfer mani-fold pipe and discharged into the retention tank.  The macerator pump withdraws material from the retention tank, grinds it and discharges it back into the retention tank.          The macerator pump has a self-cleaning feature in that it reverses and cleans itself whenever a loss in discharge pressure due to excessive solids loading is sensed.  The transfer manifold pipe is virtually free from clogging due to the action of an air induction valve which keeps waste material in the manifold pipe moving without allowing it to accumulate.

Abstract: MOLECULAR BONDED FIBER OPTIC COUPLERS      AND METHOD OF FABRICATION Abstract of the Disclosure A fiber optic coupler is formed by heating juxtaposed optically flat surfaces formed on two lengths of optical fiber to the glass transition temperature. The fibers bond together while preserving the molecular composition of the fibers at bonded region. Depending upon the depth to which the fibers are lapped to form the optically flat surfaces, the coupler may be either an evanescent field coupler or a core intercept coupler. The fibers may be mounted on curved substrates and then lapped to form the optically flat surfaces. The optical throughput of a fiber may be monitored during assembly of a coupler to permit adjustment of the positions of the optically flat surfaces to produce a desired coupling efficiency. The fibers may then be bonded together by application of energy from a suitable coherent light source such as a CO2 laser.
